Primeras evidencias de paleoterremotos en la falla de Carboneras: estudio paleosismológico en el segmento de La Serrata
A paleoseismological analysis was performed along the La Serrata segment of the Carboneras fault (Eastern Betics) in order to establish its seismic potential. The site was selected after a general geomorphological analysis of the whole fault and af ter a near-fault study of the surface geology. Tren...

| Resumo: | A paleoseismological analysis was performed along the La Serrata segment of the Carboneras fault (Eastern Betics) in order to establish its seismic potential. The site was selected after a general geomorphological analysis of the whole fault and af ter a near-fault study of the surface geology. Trenches across the fault exposed colluvial wedges, which evidenced sudden deformation events (paleoear thquakes). The Carboneras is, thus, a seismogenic fault. Evidence of a minimum of four events in the last 50 ka was detected suggesting a mean recurrence period of 14 ka. The geometry of the units and S-C structures observed in trenches indicate a lef t-lateral with some reverse component movement along the fault in its most recent activity |
